APPARATUS FOR GRINDING CARDS.

SPECIFICATION forming part of Letters Patent No. 544,441 dated August13,1895.

Application filed July 21, 1894. Serial No. 518,256- (No model.)

To all whom it may concern.-

Be it known that I, LOREN W. PENNEY, a citizen of the United States,residing at Newton Upper Falls, in the county of Middlesex and State ofMassachusetts, have invented a new and useful Improvement in Apparatusfor Grinding Cards, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, forming apart of this specification, in explaining its nature.

The invention relates to a grinding apparatus for grinding the flats ofa revolving carding-engine, and in the drawings it is represented asapplied to the grinding of the revolving flats. Broadly speaking, itcomprises a cradle or support for the grinding-roll and upon which thegrinding-roll is adjustablymounted, as hereinafter specified, and whichcradle or support is itself carried by suitable stands or brackets whichare so constructed as to permit the weight of the roll and cradle tobear upon the flat during the grinding of its wire-covered surface withany stress desired, the stress being that of the weight of the roll andthe cradle, either in whole or in part, according to the inclinationwhich the supports for the cradle may have or at which they may be set.The cradle carries adjusting devices whereby the roll is varied in itsposition both vertically and horizontally, the adjusting devices beingin the nature of compound slides. Any suitable guides may be used forbringing and maintaining the roll in proper relation to the surface ofthe flats as they are being ground.

I will now describe the invention in connection with the accompanyingdrawings,-

wherein- Figure 1 is a view in side elevation of the apparatus attachedto a carding engine. Fig. 2 is a View principally in elevation, aportion of the middle of the apparatus being removed in order that the,ends may be brought together sufficiently to show the construction ateach end. Fig. 3 is a view in elevation of the parts to the left of thedotted line w x of Fig. 2 and in section upon the said line. Fig. 4 is aview in section upon the dotted line y y of Fig. 1.

A A are brackets attached one at each side of the frame of thecarding-engine to project above it to any desired extent and at anydesired angle. Each one is formed with a section or extension 0,, theupper surface a of which forms a partial rest or support for the cradleor housing of the grinding-roll, and the pressure of the grinding-rollupon the flat varies according as the inclination of this partialsupport varies, and also according as the weight of the roll and itscradle may vary, and by varying the angle of the upper surface a' bymoving the brackets toward or from a perpendicular position the pressureof the grinding-roll upon the flat may be increased or diminished.

In Fig. 1 I have represented the brackets set at an inclination which Iconsider a desirable one for the efficient working of the device, butsuch angle, it will be understood, may be readily changed.

The cradle or housing B for the roll rests upon the surface a, and itmay be said to consist of two principal partsnamely: a frame or castingb, which extends lengthwise the roll, and compound slides at each end ofthis frame, one of which slides upon the end in one direction and theother of which slides upon the-first-named slide in a direction at aright angle to that in which thefirst-named one slides upon the frame,the second slide having the bearing for the roll.

In the drawings, 0 represents the first of these slides, which is anangular piece or casting, one section 0 of which has a guide 0', whichenters a guiding recess 0 in the end I) of the frame or casing 19, andthe slide is adjusted up and down upon this end b by means of theadjusting-screw c carried by an ear 0 of the slide, which projects overthe end b, and which screw bears upon said end, (see Fig. 3,) and theslide is locked in its adjusted position by means of the locking-screw 0(see Figs. 1 and 4,) which passes through a slot c in the slide andscrews into the end I), the screw having a washer or enlarged head whichbears against the outer surface of the slide and serves to clamp it,when screwed down hard, firmly against the surface of the end I).

The second slide is lettered D, and it slides upon the arm (1 of theslide 0, and it is adjusted thereon by means of the adjustingscrew d,(see Figs. 1 and 4,) which extends through the ear (1 and screws intothe threaded hole (1 at the outer end of the arm (I, and it is locked inany desired position by means of the locking-screw d, which extendsthrough the slot d in the slide D and screws into the threaded hole atin the arm d. The slide D is connected with the arm d by a rib orextension to enter a guideway or in any other manner to prevent it fromturning as it is being adjusted, and it has the bearing d preferably anopen one, for the shaft 6 of the grinding-roll E, the shaft having abushing e, which rests in the open bearing and which is prevented fromturning by a lug 6 which enters a hole in the hearing. A stop a extendsover the shaft or sleeve and serves to hold the roll in the hearing. Thestop is represented as formed from a rod bent ataright angle, one end ofwhich is threaded and screws into the slide D, the other end projectingover the hearing. The end plate or piece 11' carries the guide F,against the guidinging-surface of which the end of the flat is broughtinto contact and moved during the grinding operation. It will beunderstood that by means of the compound slides C D the grinding-rollmay be adjusted in relation to the line of travel of the flat in anydesired direction; it may be moved to or from such line or parallel withsuch line, or one end may be moved in either of these directionsindependently of the other, and that there is thus afforded a universaladjustment to the bearings of the roll, which permits it to be easilyadjusted in place to the proper or best position for doing its work, andwhich also does away with the fitting formerly necessary in locating thegrinding-roll.

By attaching the compound slides at each end together by means of thecross-support or connection 1), they are more rigidly, securely, andcheaply supported and the rollbearings better adjusted. In lieu of acastiron connection I) the connection between the end pieces I) maybemade by means of separate cross-rods. To prevent the cradle or supportfrom being lifted from the brackets by the belt or in any other way, Ihave formed inthe ends of the cross-piece b a pin F, (see Figs. 1 and4,) which enters the recess f on the inner side of the bracket throughthe openingf. The upper end f of this recess acts as a stop. The recessis of snfficient length to permit the adjustment of the crosssupportwith the slide 0.

It will be understood that in the above description I have described, asa rule, only one side of the device; but the other side is like it inevery respect.

The flats are caused to approach the guides F over the tables G, whichbeneath the guides are each provided with a cavity or depression g,whereby the flats while passing under the guides are thus no longerborne by the table G, but rest upon the supports H, thereby causing theweight of the grinding-roll and its housing to be carried or supportedby the working surfaces h at each end of the flats While the grindingoperation is taking place.

From what I have above stated it will be seen that the roll isadjustable vertically in relation to the guides F and horizontally anduniversally, it may be said, and this of course varies its relation tothe flats as may be desired.

It will be seen that by turning the stops e the grinding-rollE isremovable from its bearings. It will also be seen that the roll supportor saddle and the roll are removable together from the brackets A, andafter the roll has been once adjusted by the movement of its slides itis simply necessary to replace and remove the saddle and the roll as awhole when it is desired to grind the flats. It will also be seen thatthe adjusting-screws d and lockingscrews 0 d are so located as to bealways easily reached or accessible when the saddle and roll are inoperative position upon the brackets, so that the roll is easilyadjusted in place.

Having thus fully described my invention, I claim and desire to secureby Letters Patent of the United States 1.
